Use of fuzzy logic for banking risk assessment
Maňková, Veronika ; Bobalová, Martina (referee) ; Janková, Zuzana (advisor)
The thesis focuses on the use of fuzzy logic in the banking sector for credit risk assessment. Artificial intelligence, especially the fuzzy logic method, is used to construct a model for evaluating whether a client poses a threat to the bank or not based on their creditworthiness. The determination of a client's creditworthiness involves the evaluation of both financial and non-financial indicators. The paper further describes the use of the MATLAB tool for the development and implementation of this model. The resulting model allows banks to better understand credit risk and enables them to make more informed lending decisions.
Numerical methods for the analysis of light polarization in the solar corona
Gajdůšková, Kateřina ; Štarha, Pavel (referee) ; Hoderová, Jana (advisor)
This bachelor's thesis deals with the analysis of polarization of light in the solar corona. Photographs taken during a total solar eclipse are processed using software Matlab and the Image Processing Toolbox package. The main objective is to determine the polarized and unpolarized part of the light in the solar corona.

Franc, Lukáš ; Porteš, Petr (referee) ; Zháňal, Lubor (advisor)
This master thesis deals with verifying whether it is possible to determine the external speed characteristic of the engine using sensors in mobile phone. For this verification were made driving tests, during which the driving data were measured with mobile phone. These data were processed in the calculation part in MATLAB. Results were compared with power measurement on chassis dynamometer and with two alternative methods of power measurement.
Supplier evaluation in terms of risk using fuzzy logic
Marcinov, David ; Lána,, Radim (referee) ; Janková, Zuzana (advisor)
The master’s thesis deals with the evaluation of supplier risk of an unnamed company XYZ. The evaluation is done using fuzzy logic theory, which is applied in the decision model designed in MS Excel and MATLAB. Suppliers are divided into four groups with different degrees of significance based on point and percentage results. Groups get recommendations for future cooperation, eventual suggestions for procurations, which can lead to minimization of risks and more accurate fulfillment of requirements. The company XYZ need these requirements from its suppliers. Comparison of results from two different software is part of this thesis too.
Web application for antenna analysis
Večeřa, Štěpán ; Kadlec, Petr (referee) ; Raida, Zbyněk (advisor)
Měla být vyvinuta webová aplikace pro zjednodušenou analýzu anténních polí. sestávající z drátových dipólů nebo náplasťových prvků. Původně se předpokládalo, že výpočetní jádro bude vyvinuto v prostředí MATLAB a webové rozhraní v jazyce Python. Studie proveditelnosti ukázala, že plné v jazyce Python je výhodné. Vyvinuté funkce Pythonu pro analýzu a syntézu antén jsou stručně popsány a jejich funkčnost je ověřena v prostředí MATLAB.
Vibration energy harvester influence on vibration base
Nagy, Andrej ; Bajer, Jan (referee) ; Rubeš, Ondřej (advisor)
The goal of this thesis is to describe the impact of the energy harvester on the vibrating base, while also showing the basic aspects of energy harvesting. We first describe the issue on the research side, where we explain the concept and real use of energy harvesters, we show their basic construction with pictures of models and graphs from experiments showing their behavior. We also show how energy harvesters can be optimized and improved. At the end of the research part, we describe how the energy harvester can influence the deviation of the base, and therefore why it is important to model the system with a feedback impact on the base. In the practical part, we derive a mathematical model using Lagrange equations of the second kind, which we subsequently use for numerical and analytical solutions. In the final part of the work, we analyze the influence of individual parameters of the energy harvester on the output power and base deviation with the help of Matlab and Simulink.
Virtual commissioning of multi-axis manipulator
Slavík, Vojtěch ; Radil, Filip (referee) ; Štěpánek, Vojtěch (advisor)
This thesis deals with the design and virtual commissioning of multi-axes manipulator, that will be able to create figures using spherical segments according to a template. In the design, emphasis is placed on the visual appearance and simple operation of the manipulator. The thesis presents the design of the model, methods for inverse kinematics solving, communication of used software and the robot control.
Design of the system for the carbon composite conductive layers of the L-39NG aircraft testing and the optimization of the conductive material
Pham, Ngoc Nam ; Hönig,, Martin (referee) ; Háze, Jiří (advisor)
V posledních desetiletích je v leteckém průmyslu výrazně preferováno použití kompozitů. Nejnovější projekty českého leteckého průmyslu se zaměřují také na zvýšení využití kompozitů v nových letadlech. Tato práce se zaměřuje na výzkum elektrických vlastností kompozitu za účelem optimalizace výběru materiálu. Diplomová práce představuje návrh automatické měřicí stanice sloužící k měření a testování elektrických vlastností kompozitních vzorků vyráběných společností AERO Vodochody AEROSPACE as. K tomuto účelu je použito zařízení LCR bridge R&S HM8118 a řídicí program je navržen v prostředí MATLAB s použitím jazyka SCPI. Navržený systém je následně použit pro experimentální ověření elektrické vodivosti kompozitních vzorků. Výsledky měření budou základem pro vývoj kompozitů pro leteckou vodivost v nových letadlech. Tato práce také prezentuje výsledky testu úderu blesku na vybraných kompozitních vzorcích. Výsledky testu na úder blesku poskytují hlubší znalosti o schopnosti vzorků chránit před úderem blesku. V této práci je také představen vývoj nedestruktivního testovacího systému založeného na metodě elektrické impedance/odporové tomografie. Vývoj je v prvních fázích, ale očekává se, že systém bude využíván jako systém monitorování zdraví struktur.
